I live about 20 minutes away from Samlesbury Hall.
Not sure if the pictures are still there, we do have a number of images that we have taken but none that show the pictures concerned.
There is not to much original pictures and furniture in the Hall given its size, it used to be used as an antiques centre but now its open for visitors to roam around the Hall and grounds
We have had a particularly good reason to visit the Hall in that my Wife is a descendent of the Southworth and Stanley families. One of the images we took is of the Southward family tree to which you are welcome to have a copy, pm me with your email address.
